Alumina ceramics have excellent insulation, low high-frequency loss but good high-frequency insulation, so what are the properties that alumina ceramics will improve after machining? Next, Pintejin ceramics will introduce to you. 1. Improve hardness The Rockwell hardness is up to the standard. Taking the processed wear-resistant ceramic patch as an example, its hardness is second only to that of diamond. It was found after many experimental verifications by alumina ceramic manufacturers. Physically speaking, after the alumina wear-resistant ceramic patch is processed, its hardness far exceeds the wear resistance of stainless steel and wear-resistant steel. It can be seen that its hardness is significantly improved after machining. 2. The wear resistance Read more

Pintejin Ceramics Factory is a professional manufacturer of precision ceramics machining, which can provide customized precision ceramics machining and production according to drawings. Below, Pintejin Ceramics Factory will introduce the sintering technology of precision ceramics to us. Precision ceramic nozzle The sintering technology of precision ceramics mainly includes the following methods: Atmospheric pressure sintering of precision ceramics, also known as pressureless sintering. It belongs to the process of free sintering of the green body under atmospheric pressure. In the absence of external power, the sintering temperature of the material generally reaches the melting point of the material at 0.5-0.8. Solid-phase sintering at this temperature can induce sufficient atomic diffusion in Read more

Although the zirconia ceramics we are familiar with have excellent performance and high hardness, it will inevitably require very precise machining during machining. Next, the Pintejin ceramics manufacturer will introduce to you the finishing methods and attention of zirconia ceramics. point. Finished zirconia ceramic tube Processing method of precision zirconia ceramic machining: Zirconia ceramic machining methods are commonly divided into two categories: mechanical machining, mold injection machining, etc. Among them, the mechanical machining method is highly efficient, so it is widely used in industry. Applications, especially diamond wheel grinding, lapping and polishing are common. Precautions for machining precision zirconia ceramic parts: Although there are many methods for machining precision zirconia Read more

Alumina ceramics are made by using alumina as the main raw material, adding 6-30% of clay, magnesium oxide, calcium oxide, titanium oxide and other sintering accelerators, and sintering at 1450-1800 ℃ after mixing. The more alumina content, the better the inherent properties of alumina can be exerted, and the better the performance, but it becomes difficult to manufacture as the alumina content increases. The characteristics of alumina porcelain are that it still has good insulating properties at high temperature. Pure alumina porcelain can be used at a temperature of 800 ° C. Its mechanical strength is the highest among all oxide ceramics, and its thermal conductivity is large and thermal Read more
